In order to improve the excellent properties of piezoelectric ceramic materials, mechanical alloying by high energy ball milling was successfully employed to synthesized lead zirconate titanate (PZT).
It has been shown that the chemical reactivity of starting materials could be improved significantly after using this technique.
Previously, there are four major sintering parameters that control the microstructure and properties of PZT ceramic materials which are temperature, heating rate, duration and atmosphere [2].
PbO (Aldrich, 99 %), TiO2 (Merck, 99 %), ZrO2 (Merck, 99 %) and 10 wt % excess PbO were used as starting materials.

A kind of new method and new tool is offered to three-dimensional discrete element method performance analysis and optimization design, and three-dimensional discrete element method belongs to relevant mechanical components contacted and acted with granular materials.
While the different physic mechanical characters of different materials boundaries should be considered in the set of material characteristics parameters.
method analysis mode and contact mechanics mode and parameters of granular materials, therefore, there is wide application prospect for this software.

It is found that the localized plasticity patterns emergent in nanocrystalline materials are in a way quite distinct from those of ultrafine grain materials [4-6].
The deformation is liable to localize on the macro-scale level in ultrafine grain materials, which will directly determine the failure behavior in these materials [7].
This observational result can be used for certification of materials having nano- and submicrocrystalline structure.
